I ran my first half marathon yesterday. I didn’t train for it in any
calculated way, and I didn’t really plan it. After work, I checked Google
Maps for the approximate distance of my route, closed my laptop, and started
running. And although I left open the possibility of cutting a shorter loop,
or turning around early, in the end I just kept running the whole 13 miles,
just like I thought I knew I could.
上面的这句话 “And although I left open the possibility of cutting a shorter loop, or turning around early, ”
有高手能帮忙看一下这是什么意思吗? I left open是什么东西.....
cutting a shorter loop 又是什么东西...
非常感激~

看前面的语意 应该是有抄近路的可能性吧 因为他只是大概看了下地图

left open the possibility=保留了可能性意思是他一开始估计有可能需要抄捷径或提早折返但实际跑了之后他跑完了全程
